GIS를 활용한 경제림 육성단지 등급 구분 및 활용

Abstract

The purpose of this research is to provide supporting data for current and future managementof economical forest growing sites by classifying them(high/medium/low) and developing adigital map. To achieve this goal, we examined the characteristics of economical forest growingsites, developed the method to classify, and represented the result of their classification. Economical forest growing sites are classified into 3 grades(Grade I·II·III) with maps of timberproduction function and forest lands of public interest(except natural recreational forest) usingGIS overlay analysis. High timber production function areas are assigned to Grade I, the rest ofeconomical forestlands are assigned to Grade II, and All areas are reassigned to Grade IIIconsidering the existence of forest lands of public interest. The result of classification forEconomical forest growing sites was 2,083 thousand ha(71.9%) of Grade I, 499 thousandha(17.2%) of Grade II, and 267 thousand ha(9.3%) of Grade III. As the result of case studiesfor pioneer forest management sites, Hongcheon, Jinan, and Boseong sites were mostly occupied by Grade I. Therefore, the classification of economical forest growing sites can be used todesignate future pioneer forest management sites, and it can be a foundation to have anintensive promotion for sites which have relatively high productivity.
